Product Details
 

概述
  QX9920 是一款高效率，稳定可靠的高亮度LED灯驱动控制IC，内置高精度比较器，off-time控制电路，恒流驱动控制电路等，特别适合大功率，多个高亮度LED灯串恒流驱动。
  QX9920采用固定off-time控制工作方式，其工作频率可高达2.5MHz，可使外部电感和滤波电容、体积减少，效率提高。
  在EN端加PWM信号，可调节LED灯的亮度。
  通过调节外置的电阻，能控制高亮度LED灯的驱动电流，使LED灯亮度达到预期恒定亮度，流过高亮度LED灯的电流可从几毫安到1.5安培变化。
       特性

 可编程LED驱动电流，编程范围为10mA到1.5 A
 高效率：90%
 输入电压范围：2.5V~400V
 工作频率可调：500KHz~2.5MHz
 驱动LED灯功能强：LED灯串可从1个到几百个LED高亮度灯
 亮度可PWM可调：通过EN端，调节LED灯亮度
       应用
  大功率LED照明设备
  LED灯杯
  LED筒灯
  LED手电筒
